TO ALL WHOM IT MAY oononnn:

Be it known that I, .IOHN LAWRENCE KLEIN, of the city of New York, Stateof New York, have invented a new and improved Mode of Making Soap; and Ido hereby declare that the following is a full and-exact descriptionthereof. a

The nature of my invention is as follows:

To make this soap, and to enable others skilled in the art to make anduse my invention, I will nowproceed to describe the diiferent processesor'compositions of,matter used in its manufacture.

I use three dili'erent lyes, numbered, respectively, one, two, andthree, their strength being measured, in all the different processes, byBaum's hydrometer, and which can, by addition of water, he reduced toany strength required.

Lye No. 1. I take two thousand pounds (2,000 lbs.) of barilla, mix withit one thousand two hundred pounds (1,200 lbs.) unslakod lime, place thewhole into a tank, and pour cold water upon it, until the water standssix or eight inches above the mixture. Stir it well, and let it restuntil clear. When so, this lye will be of a strength of abouttwenty.(20) or twenty-five degrees, and is ready to be used. I

Lye No. 2. I place into an iron kettle, heated upon open fire, or by dryor wet steam, six hundred pounds (600 lbs.) of caustic soda. Add to itone hundred gallons (100 gels.) of cold waters Let this mixture boiluntil the caustic soda is dissolved. When so, this lye will be of astrength of thirty-five to forty (40) degrees, and ready to be used.

Lye No. I place into an' iron kettle, heated as in Lye No. 2, onethousand (1,000).pounds of salt soda. Add to it one hundred and fifty(150) gallons of cold water. Let it boil until the soda is dissolved.When so, I add three hundred (300) pounds of unslaked limo. Let it againboil until the lime-is dissolved. When so, I place all of it into atank. Let it settle until clear. When clear, this lye will be ofa'strcngth of about twenty five (25) to thirty (30) degrees, and readyto be used.

This finishes the processes of making the three difierent kinds of lyes,which can now, by addition of water, be reduced to any degree ofstrength required.

To complete the soap, I proceed as follows:

I place into an iron kettle, heated as mentioned before, one thousand(1,000) pounds of tallow. Add to it one thousand (1,000) pounds ofgrease, two hundred (200) pounds of palmoil, twenty-five (25)'pounds ofpotash, sixty-four (64) gallons of cold n'ater, aud let all boil for one(1) hour. 'lhen I add one hundred (100) gallons of Lye No. 1, firstreduced to fifteen (15) degrees of strength. Let it again boil for one(1) hour. When so, I add one hundred (100)v gallons of Lye No. 2, firstreduced to'fifteen (15) degrees of strength. Let all again boil for onehour, after which time this compound will be what I term glue-soap. ThenI add common salt, in small quantities, until the lye separates from thegluc soup. Let it rest for two hours, without fire or steam, until allthe lyc has settled to the bottom of the kettle. When this is done, Iplace a pump into the kettle, and

pump out all the lye collected at the bottom. .Then I add onehundred-(100) gallons of Lyo' No. 1, and one hundred (100) gallons ofLye No. 2, both first reduced to fifteen (15) degrees of strength. Letall boil for half an hour. Then Iadd two hundred (200)pounds of rosin.Let all boil for two hours. When so, I add common salt, in smallquantities, until the lye has separated from the soap. When so, I letall stand until the lye has settled to the bottom. Then Ipump all thelye out in thesamo manner as stated before. Then I add one hundred (100)gallons of Lye No. 1, first reduced to five degrees of strength, and onehundred gallons of Lye No. 2, first reduced to ten (10) degrees ofstrength. Let all boil until no more foam is produced on the surface,which will take from five to eight hours, during which time I add everyhour tu'entyefivc (25)'pounds of each of last-named lyes. Then I coverthe kettle, and let the lye settle to the bottom. When so, I introduce apump, as before stated, and pump all'the lye out. Then will remainu'hatI' term separated soap. Now, I add, keeping all well heated, littleby little, one hundred gallons of water. Let all boil for about half anhour, take out the fire, or'turn oil the steam, cover the kettle well,and let it remain for about eighteen (18) hours.

Now, I place into another boiler two hundred (200) pounds of cocoa-oil.Let it heat gradually to about thirty-five (35) degrees Fahrenheit. Addto it two hundred (200) pounds of Lye No. 3, twenty-five (25) degreesstron Stir it until well combined. when so, this will be what I termeoeoznsoap. This I keep warm, and introduce, under constant stirring,all of the above-named separated soap. Keep on stirring until all iswell combined and looks smooth. When so, I pour this mixture, underconstant stirring, into soap-frames, and keep stirring in the framesuntil thick. Let it stand until hard. When so, the soap is finished.

What I claim as my invention, and desire to secure by Letters Patent,is-

A new and improved process for making soap, as herein described, usingfor that purpose the aforesaid ingredients or compositions of matter, orany other substantially the same, and which will produce the intendedotlect.
